APT-4-11 4-port PoE switch 10/100Mbps, extender

APT-4-11 is an PoE network switch working as an extender (repeater) of LAN and PoE power. It is most commonly used when several network devices (e.g. several IP cameras) need to be run on a single UTP cable, or when an additional network branch is required.

The device allows us to power up to 3 PoE receivers using a single UTP cable. In situations where there is no possibility of supplying a new cable, or where supplying a new cable would be expensive, the APT-4-11 allows us to use the existing cabling.

APT-4-11 can act as a LAN + PoE extender in situations where the distance between devices exceeds 100m. If it is possible to split the cable into sections under 100m of UTP cable, it allows us to extend the range of the LAN without the need for additional power supply, while maintaining full 100Mbps throughput.

The built-in LR150 (Long Range 150m) function allows all ports to operate stably up to 150m of UTP at 100Mbps with PoE power. This will enable the installation of cameras without the use of an additional intermediate extender.

Basic applications:

• as splitter for 3 PoE receivers (IP cameras) powered by a single UTP cable, e.g. installation of additional cameras in place of existing cameras without changing the cabling
• in cascade connection (series) for connecting several PoE IP devices over distances exceeding 100 m of UTP cable
• the possibility of local power supply allows to build a complex structure of distribution points in extensive installations

APT-4-11 is designed to cooperate with any network devices, IP cameras and other devices powered by PoE 802.3af/at standard.

The APT (Atte Power Tree) series provides compatibility with IEEE 802.3af/at/bt standards as PoE receivers and IEEE 802.3af/at on all output ports. When a device is connected to output ports 2-4, the receiver is identified and, if it is a PoE-powered device, power is switched on at the port.

The APT switch has the possibility to be powered from an external power supply via an additional screw connector, in which case LAN port 1 is used as a LAN network port (without PoE power supply).

The PoE identification standard, the operating status and the available power for the receivers are indicated via LEDs:

• PWR - device is powered
• LED at - identification as 30W PoE receiver
• LED bt - identification as a 60W PoE receiver

Key features and functions:

• can be powered from another PoE switch in 802.3af, 802.3at, 802.3bt or PoE Passive standard (PoE IN port)
• amplifies and distributes the network signal (fully functional 100Mbps switch)
• cascaded power supply (one switch powers another)
• ability to power up to 3 PoE 802.3af/at receivers
• up to 60W total power when powered via UTP
• built-in LR150 function increases the maximum transmission distance to 150 metres
• clear signalling of operating status and identification
• low power consumption (< 0.5W)
• quick and easy commissioning without configuring parameters
• wide operating temperature range

APT-4-11 has a polycarbonate base equipped with mounting holes. It allows mounting with ADD-PIN pins in the 10.8mm grid that is found in ABOX series enclosures and mounting plates and adapters fitted with holes.

The device has a protection level of IP20, a suitable enclosure (minimum IP44) is required to ensure protection from the elements and condensation.

The enclosure allows mounting in several ways:

• with the use of mounting pins on a 10.8 mm raster, which is used in all ABOX enclosures
• with the use of mounting studs for RACK 19" and RACK 10" adapters
• by screwing through the additional holes to any flat surface

Installation notes 

The total power consumed by the cameras (PoE receivers) connected to the extender must not exceed the power budget offered by the switch powering the entire line:

• for 802.3af standard it is approximately 13W available on the extender
• for 802.3at standard it is approx. 25W available on the extender
• for 802.3bt60 standard it is approx. 51W available on the extender

Take into account IR illuminators - they turn on at night, increasing power consumption significantly.

Also consider the loss in the power cable - this depends on its cross-section, length and the voltage value on the PoE line.
